2.2 Personnel qualifications
The installation, operating and maintenance personnel must
have the appropriate qualifications for this work. Area of
responsibility, terms of reference and monitoring of the per-
sonnel are to be ensured by the operator. If the personnel are
not in possession of the necessary knowledge, they are to be
trained and instructed. This can be accomplished if necessary
by the manufacturer of the product at the request of the oper-
ator.
2.3 Danger in the event of non-observance of the safety
instructions
Non-observance of the safety instructions can result in risk of
injury to persons and damage to the environment and the prod-
uct/unit. Non-observance of the safety instructions results in
the loss of any claims to damages.
In detail, non-observance can, for example, result in the follow-
ing risks:
• Danger to persons from electrical, mechanical and bacteriolog-
ical influences
• Damage to the environment due to leakage of hazardous mate-
rials
• Property damage
• Failure of important product/unit functions
• Failure of required maintenance and repair procedures.

6 Description and function
6.1 Description of the product
Series SB circulating water service pumps have been specially
designed for use in conjunction with domestic/ drinking water
service systems. They are, by material selection and design,
corrosion proofed against any residual parts in domestic/drink-
ing water.
The pump consists of a hydraulic system, a glandless pump
motor with terminal box. All the rotating parts in the glandless
pump are in contact with the fluid, this is also true for the motor
rotor. A shaft sealing, which is subject to wear, is not necessary.
The fluid lubricates the slide bearings and cools the bearing and
the rotor. Motor protection is not necessary. Even the maximum
overload current cannot damage the motor. The motor is
blocking-current proof.
6.2 Function of the product
Variable speed control (Fig. 3)
The pump's speed is switched in three stages [1 – 2 – 3] using
a rotary knob. The speed in the smallest stage is approx. 40 to
50 % of the maximum speed with a reduction of the current
consumption to 50 %.
7 Installation and electrical connection
DANGER! Risk of fatal injury!
Improper installation and electrical connection can result in
fatal injury.
• Installation and electrical connection may only be carried out
by qualified personnel and in accordance with the applicable
regulations.
• Adhere to regulations for accident prevention

English
10 WILO SE 04/2013
7.1 Installation
• Install directly on a horizontal or vertical pipe, on the distribu-
tion circuit return, after the draw off points (Fig. 1).
• Only install the pump after all welding and soldering work has
been completed and, if necessary, the pipe system has been
flushed through.
• Install the pump in a readily accessible place for easy inspection
and dismantling.
• Install gate valves upstream and downstream of the pump to
facilitate a possible pump replacement.
• Perform installation so that any leaking water cannot drip
onto the control module.
• To do this, align the upper gate valve laterally.
• Install with the power switched off and the pump motor always
in a horizontal position.
See Fig. 2 for installation positions of the pump.
• Direction arrows on the pump housing indicate the direction of
flow (Fig. 3, item 1).
• In thermal insulation work, make sure that the pump motor and
the module are not insulated. The condensate-drain openings
must remain uncovered (Fig. 3, item 2).
• Use a open-end wrench to prevent the pump from twisting (Fig. 5).
• The motor housing can be twisted after undoing the motor
attachment screws if it is necessary to position the terminal box
(Fig. 4).
Note: Generally, turn the motor head before the system is filled.
When turning the motor head in an installation which is already
filled, do not pull the motor head out of the pump housing. Turn
the motor head with a small amount of pressure on the motor
unit so that no water can come out of the pump.
CAUTION! Risk of damage to property!
The gasket may be damaged when the motor housing is
turned. Replace defective gaskets immediately:

7.2 Electrical connection
DANGER! Risk of fatal injury!
A fatal shock may occur if the electrical connection is not
made correctly.
• Only allow the electrical connection to be made by an electri-
cian approved by the local power supply company and in
accordance with the local regulations in force.
• Disconnect the power supply before any work.
• The current type and voltage must correspond to the details on
the rating plate.
• The electrical connection must be made via a fixed connected
load. The latter is provided with a plug device or an all-pole
switch with a contact opening width of at least 3 mm.
• To ensure drip protection and strain relief at the PG screwed
connection, a connected load with an adequate outer diameter
is necessary (e.g. H05W-F3G1.5 or AVMH-3x1.5).
• The connected load is to be installed in such a way that it can
under no circumstances come into contact with the piping
and/or the pump and motor housing.
• Make the mains connection corresponding to the terminals of
the circulator: Live (L), Neutral (N), and Earth (M) to (Fig. 6).
• The connection cable can be taken through the cable feed-in right
or left. Exchange dummy plugs and cable feed-in as necessary.
When the terminal box is positioned laterally, always arrange the
cable feed-in from below.
CAUTION! Risk of short circuit!
Once electrical connection is complete and in order to pro-
tect the terminal box from moisture, the terminal box cover
must be sealed according to regulations.
• Earth the pump/system according to regulations.

8Commissioning
WARNING! Risk of injury and damage to property!
Incorrect commissioning can lead to injuries to persons and
damage to property.
• Commissioning by qualified personnel only!
• Depending on the operating status of the pump or system
(fluid temperature), the entire pump can become very hot.
Touching the pump can cause burns!
8.1 Filling and venting
Fill and vent the system correctly.
The pump does not pump any water if there is air in the pump
room. The pump rotor compartment is vented automatically
after a short operating period.
Dry running for short periods will not harm the pump.
Please proceed as follows if it is necessary to vent the rotor
room:
• Switch off the pump.
WARNING! Danger of personal injury!
Depending on the operating status of the pump or system
(fluid temperature), the entire pump can become very hot.
Touching the pump can cause burns!
• Close the gate valve on the pressure side piping.
WARNING! Danger of personal injury!
Depending on the temperature of the fluid and system pres-
sure, when the venting screw is opened, hot liquid or gaseous
fluid may escape or shoot out at high pressure. Escaping fluid
can cause scalding!
• Undo the venting screw carefully a few turns (Fig. 7).
• Protect electrical parts from any escaping water.

•Switchonthepump.
Note: The pump may jam if the venting screw is undone,
depending on the operating pressure level.
• Screw the venting screw back in again after 15 to 30 seconds.
•Openthegatevalveagain.
8.2 Variable speed control
The circulator flowrate is adjusted by changing the speed of
rotation of the motor using the selector switch (see Fig. 3).
9Maintenance
DANGER! Risk of fatal injury!
A fatal shock may occur when working on electrical equip-
ment.
• The pump should be electrically isolated and secured against
unauthorised switch-on during any maintenance or repair
work.
• Any damage to the connection cable should always be recti-
fied by a qualified electrician only.
After successful maintenance and repair work, install and con-
nect the pump according to the “Installation and electrical con-
nection” chapter. Switch on the pump according to the
“Commissioning” chapter.
